It's not always running, I guess?  (My GET requests are timing
out.)  Have you tried a GET coming from outside the organization
and thus outside whatever firewall may be between the W3C server
and sirius-software.com:9204 ?

Did View Source show anything else?

=46rom your description, I can't see that you are doing anything
wrong.  Without your system actually running, though, and serving
the data, it's hard to see what's wrong.  So I'll just tell you
what you already know:

  - Maybe the problem is in your Web server.  You've checked
    this by issuing a GET on the documents individually.

  - Maybe the problem is in the connection between the W3C
    server and your Web server.  Do people outside your domain
    have access to your port 9204?

  - Maybe the problem is that your sample data or schema are
    rolling XSV over.  Do other validators have a problem?
    (If you don't have a validator installed locally, you might
    try any of XSV, Xerces J, Xerces C++, MSV, or ...)

  - Maybe the problem is at the interface between what the XSV
    Web interface sends back and what your browser expects;
    Does the same problem occur if you check the button for
    getting the results labeled text/plain?  Do other browsers
    (lynx?  IE? Galeon? Netscape?) do the same thing?
